Rear window replacement

[lowNslow]

I am in the process of replacing the door and rear windows and having difficulty in finding the seals. Has anyone done this lately, and if so what did you use for seals. The parts manual does not seem to have a part number for the rear window and the door window part seems to have been superceded by something that is sold by the foot (u channel ?) according to "iwantcessnaparts.com".

The official Cessna replacement part number is: S1152-1-84-00W for the front window seals.* It is a grey rubber double-"U" channel, 84" long for both windows, that is glued to the metal door frame with 3-M 1300L adhesive. It is available from any Cessna Distributor such as Yingling 800-854-2647 (http://www.yinglingaircraft.com/) or Hill Aircraft 800-998-7832 (http://www.cessnaparts.com/) who has it priced at $31.03.
The rear windows are held in place by their metal retainers and a rubber U-channel. It is available from Brown Aircraft Supply (904-396-6655) as their pn: BA-200 sold by the foot.
Hope this helps.

My personal favorite window seal is:

Thanks George. Is the S1152-1-84-00W seal the window to window-frame seal or the window to door seal? When using the straight U-channel for the rear window, but how do you get it conform to the radius on the rear windows without crimping?

The window seal, Fig Pg. 60, Fig. 33, item 58, PN 0511106-105 is superceded to S1152-1-84-00W. The BA-200 (Brown Aircraft PN) is used for both front and back windows and is a suitable replacement for original PN 0511106-103 (Fig 33, item 52) and is the same material as used beneath item 5 and un-identified on Pg. 45.

Please Note: PN 0511106-103 has been superceded at Cessna, and is now available under PN R761483 priced at $1.31/ft. (Yingling 800-854-2647 (http://www.yinglingaircraft.com/) or Hill Aircraft 800-998-7832 (http://www.cessnaparts.com/) can obtain this for you.)

Placed in hot water before installation and stretched tightly around the glass-edge, the seal will conform more easily without crimping.

Or, if you are very very careful you can replace the window and re-use the seals from the old window.

New reply to old thread. Given the youngest of our 170s is 64 years old, and the rubber seal around the window "glass" may be original, I seriously question the advisability of using the original seal. Has anyone else noticed over the years, that the majority of repairs we accomplish, have causes that trace back to something made of rubber.

I seem to remember that window seal material being very similar if not identical to the rubber u-channel found in several places on the exterior of he airplane. If anyone still has any of that stuff that’s 60+ years old, it could probably be ground to about the consistency of black pepper between your finger and thumb by now. I don’t think a few feet of new material is going to break the bank.

The common rubber channel stuff works fine. It's cheap and will last longer than you plan on using the airplane. The old one seemed fine as installed - stiff but no leaks - but it was in 20 pieces as the window came out.

I found that the downside of replacing the rear windows with new was that I now need to replace the forward (door) windows that looked pretty good before.
